ATTACHMENT FOR ron-Boxes.

Specification of Letters Patent.

Patented Oct. 1, 1907.

Application filed April 11, 1906. Serial No. 311.170.

To all whom it may concern:

Be it known that I, WINFIELD W. STEVENSON, a citizen of the United States, residing at Philadelphia,

in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Attachment for Ice-Bones, of which the following is a specification.

This invention relates to attachments for ice chests and refrigerating apparatus of the larger sizes, and has for its object to provide means whereby artificial light is furnished to the interior when the door is opened.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within ,the scope of the appended claims.

In the accompanying drawings forming a part of this specification and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of the invention capable of carrying the same into practical operation.

In the drawings:Figure 1 is a sectional view including a portion of one of the walls and a portion of the door of an ice chest or refrigerator, with the improved device applied. Fig. 2 is a view of the parts shown in Fig. I viewed from the interior of the ice. 7 Fig. 3 is a sectional detail on the line 3-3 of A chest. Fig. 1. Fig. 4 is a sectional detail, illustrating modifications in the construction of some of the parts.

The wall of the refrigerator is represented at 10 and a portion of the door at 11.

Attached to the Wall 10 at a point convenient to the doorway opening and adjacent the latch side of the door, is a base member 12, having spaced posts 1314 extending therefrom, the posts having a switch arm-15, the switch arm pivoted at 16 in the post 13 and adapted to be connected with and disconnected from the post 14, in the usual manner, to open and close an electric circuit as hereafter explained.

The base member 12 is provided with spaced porcelain bushings 17 1 8' through which'the conductors l9 and 20 respectively pass. The conductor 19 connects with the post 14 and the conductor 20 with the post 13. In the conductor 19 is connected an arc light 21 preferably of the incandescent type. When the knife switch is closed, the current passes from a suitable source of electro motiveforce through the conductor 20, post 13, thence through the blade 15 of the switchto the post 14, and then through the conductor 19 and lamp 21 to the source.

Attached to the wall 10, preferably to the lintel of the doorway openings, is a casing 24 having a bolt 25 slidably disposed therethrough, and with a spring 26 within the casing and operating to support the boltyieldably in withdrawn position. The bolt 25 is adapted to bear against an extension 27 from the switch arm 15, the connection between the bolt 25 and switch arm being either by a supplemental arm 28, as shown in Fig.1, or by direct contact with the bolt, as shown in Fig. 4. The end of the bolt 25 next to the door 11 is preferably forked, and adapted to be engaged by a spring controlled bolt 29 operating in a casing 30 attached to the door, the spring 31 of the bolt 29 operating to maintain the bolt normally in its projected position, as shown in Fig. 1. The bolt 29 projects at 32 in advance of the casing 30, and is provided at the projecting end with a pull chain 33, so that the bolt 29 may be actuated manually from within the refrigerating chamber. The casing 30 and the bolt 29 are so disposed relative to the bolt 25 that when the door is closed the bolt 29 will bear against the bolt 25 and force it inwardly, carrying the switch bar 15 with it by its contact with the extension 2 7, and thus break the circuit by disconnecting the switch bar-from the post 14 and cut out thelight 23. When the door is open, the bolt 29 is withdrawn from the bolt 25 permitting the spring 26 to withdraw the bolt 25 and permitting the switch bar to be closed into the post 13 by the operating spring 34, and thus close the circuit and cut in the light. Thus th 0 interior of the refrigerating chamber is automatically illuminated when the door is open, and the light automatically shut off when the door is closed.

The refrigerating chambers to which devices of this character are applicable are generally quite large, frequently in the form of large rooms, in which men are frequently employed in changing and rearranging the contents, and it frequently happens that it is desirable to close the door while the workmen are thus employed, and when this occurs it is necessary that artificial light be provided, and this may be readily done by simply drawing downward upon pull chain 33 and thus releasing the bolt 25 and cut in the light.

The device is simple in construction and can be readily applied without. material modifications to the various forms of refrigerating chambers manufactured.

Having thus described the invention, what is claimed as new is 5- 1. The combination of a lamp circuit, a switch for controlling the circuit, a wall, a movably mounted member arranged on the wall to actuate the blade of the switch, a door, a device arranged on the door to strike and move the member as the door is swung closed, and means attached to the said device for moving the same out of engagement with the member.

2. The combination of a lamp circuit, a switch for con trolling the same, a wall, a member movably mounted on the wall adjacent the switch and arranged to actuate the blade of the latter, a door, a device arranged on the door to strike and move the member for opening the switch, a manually controlled means for disengaging the device from the member, and means for actuating the member when the said device is released from the latter.

3. The combination of a chamber having an opening. a closure for the opening, a lamp for illuminating" the interior of the chamber, :1 circuit for the lamp, :1 switch for the circuit having a tendency to close the latter, a

spring controlled boltarranged to hold the switch open and when released to permit the latter to close automatically; and a controllable means carried by the cl'osure carried by one of the walls of said chamber and engaging laid controlling means, a spring controlled bolt carried by said closure and adapted to operate said first-mentioned bolt when the closure is closed, and means for actuating the bolt carried by said closure from within-said chamber.

In testimony thatHI claim the foregoing" as niy own, I

have hereto aflixed my signature in the presence of two 15 'witnesses. w
